Geniculate

Geniculate is a term used to describe certain insect antennae. Geniculate antennae are bent or hinged sharply, almost like a knee or elbow joint. The term geniculate derives from the Latin genu, meaning knee.

Geniculate is a morphological form of antennae found in some groups of insects, especially in ants or bees.
